    Abstract Pelvic exenteration surgery is used as a standard procedure in recurrent pelvic cancers. Total pelvic exenteration (TPE) includes resection of the uterus, prostate, ureters, bladder and rectosigmoid colon from pelvic space. Empty pelvis syndrome is a complication of the TPE procedure. Following TPE, complications such as haematoma, abscess leading to permanent pus discharge and chronic infections can occur. Herein, we present the case of a man in his 50s who was referred for pelvic pain, foul-smelling discharge and non-functioning colostomy, and operated for distal rectal cancer 1.5 years ago and underwent low anterior resection. In this case, we performed TPE for the recurrent tumour. To prevent TPE complications, we used a breast implant for filling the pelvic cavity. The early and late postoperative course was uneventful.

    Abstract Laparoscopic colon surgery has become a proved method for the resection of both benign and malignant disease. With the advance of technological innovations and surgical experience, more complex laparoscopic procedures including restorative proctocolectomy have become increasingly used in the treatment of ulcerative colitis with safe and feasible results. When these operations are realized in a stepwise fashion, the complexity of the procedure becomes simplified. The technical aspects of laparoscopic restorative proctocolectomy in patients with ulcerative colitis are reviewed in this article. A J-pouch with a stapled anastomosis has been the preferred technique because it is quicker and safer. In all patients diverting loop ileostomy is regularly created at the time of ileal pouch-anal anastomosis. In this review the postoperative results are also revised. Postoperative fasting time, postoperative hospital stay, and overall complication rate are in favor of laparoscopic technique when compared to open approach. However, clinical value of laparoscopic surgery for ulcerative colitis needs further evaluation with more well-designed randomized controlled trials along with long-term follow-up.

    Abstract Objective: In this study, we aimed to compare long term oncological outcomes of upfront surgery versus neoadjuvant treatment in patients with locally advanced gastric cancer.
    Methods: A total of 183 patients who were operated for gastric cancer were retrospectively analyzed. The patients received either standard gastrectomy or preoperative NACT + gastrectomy. Neoadjuvant therapy was administered with FLOT regimen (docetaxel, oxaliplatin, fluorouracil, and leucovorin) or DCF regimen (docetaxel, cisplatin, and 5-fluorouracil).
    Results: Of the patients receiving NACT, 33 received FLOT regimen and 14 received DCF regimen. The number of male patients was higher in both standard gastrectomy and NACT + gastrectomy groups (p=0.385). Leukopenia and neutropenia were the most common hematological toxicities, while anemia and nausea were the most frequent non-hematological side effects in the both of NACT group. The outcomes of the grades of postoperative complications according to the Clavien-Dindo classification is similar between groups. There was no statistically significant difference in the length of hospital stay after surgery between the groups (p=0,001). According to the disease stage, it was found no statistically significant difference in the OS and DFS between the NACT and standard gastrectomy groups.
    Conclusion: Although we found no significant difference between the patients undergoing standard gastrectomy and those undergoing NACT before gastrectomy, we believe that NACT may contribute to the favorable prognosis of patients with locally advanced disease with improved OS and DFS and this should be examined in future studies.

    Abstract Purpose: To investigate the performance of computed tomography (CT) in the local staging of colon cancer in different segments, with emphasis on parameters that have been found to be significant for rectal cancer, namely, extramural venous invasion (EMVI) and tumor deposits (TDs).
    Methods: CT and pathology data from 137 patients were independently reviewed by radiology and pathology teams. The performance of CT in categorizing a given patient into good, versus poor prognostic groups was assessed for each segment, as well as the presence of lymph nodes (LNs), TDs and EMVIs. Discordant cases were re-evaluated to determine potential sources of error. Elastic stain was applied for EMVI discordance.
    Results: The T staging accuracy was 80.2%. For T stage stratification, CT performed slightly better in the left colon, and the lowest accuracy was in the transverse colon. Under-staging was more common (in 12.4%), and most of the mis-staged cases were in sigmoid colon. According to the first comprehensive correlative analysis, the sensitivity, specificity, and accuracy of CT for detecting TDs were found to be 57.9%, 92.4%, 87.6%, respectively. These figures were 44.7%, 72.7%, and 63.5% for LN, and 58.5%, 82.1% and 73% for EMVI. The detection rate was better for multifocal EMVI. The detection rate was also comparable (although substantially underestimated) for LNs, with the half of the LNs missed by CT being < 5 mm. Four patients that were classified as TD by CT, disclosed to be LNs by pathology. Correlative analysis led to refinement of the pathology criteria, with subsequent modifications of the initial reports in 13 (9.5%) patients.
    Conclusion: Overall, CT performed well in the evaluation of colon cancer, as did TD and EMVI. It is advisable to include these parameters in CT-based staging. Radiologists should be aware of the pitfalls that occur more commonly in different segments.

    Abstract Purpose: Differentiation of the histopathologic subtypes can be clinically important as it can affect the course of treatment and the prognosis. The aim of this study was to investigate both the clinicopathological features and prognosis of histologic subtypes in right-sided colon cancer.
    Methods: This study included 138 patients who underwent surgery for right-sided colon cancer. The patients were divided into three groups according to histopathological subtypes as follows: medullary carcinoma (MC, n=11), mucinous adenocarcinoma (MAC, n=29), and classic adenocarcinoma (AC, n=98). The groups were compared in terms of demographic characteristics, type of surgery, pathological outcomes and survival.
    Results: The rate of laparoscopic surgery was significantly lower in the MC group compared with MAC and AC groups (45.4% vs 54.5% vs 35.7%, respectively, p=0.001). In MC group, T4 stage was significantly higher than in other groups (90.0% vs 34.5% vs 35.7%, respectively, p=0.001). While patients with MAC had no distant metastasis, 18.2% and 15.3% of patients with MC and AC respectively, had distant metastasis (p=0.07). MAC vs MC, p=0.01, MAC vs AC, p=0.03). Tumor size, tumor volume, and the rate of microsatellite instability were found significantly higher in the MC group (p<0.05). The 5-year overall (OS) and disease-free survival (DFS) were better in the MAC group compared with MC and AC groups, but these differences did not reach statistical significance (OS: 92.8% vs 72.7% and 68.7%, p=0.16 and DFS 87.3% vs 58.2% and 64%, p=0.10, respectively).
    Conclusion: MC is associated with more advanced tumor size and T stages, and therefore entails reduced rate of minimally invasive procedures. In our series, the absence of distant metastasis in the patients of MAC also had a positive effect on survival.

    Abstract Purpose: The aim of this study was to compare ghost ileostomy (GI) and defunctioning ileostomy (DI) in patients who underwent low anterior resection (LAR) for rectal cancer in terms of postoperative morbidity, rehospitalization rates, and total costs.
    Methods: Patients with an anastomosis level between 5 and 10 cm from the anal verge after LAR were analyzed retrospectively. Clinical characteristics, operative outcomes, postoperative morbidity, rehospitalization rates, and total costs were compared.
    Results: A total of 123 patients were enrolled as follows: 42 patients in the GI group and 81 patients in the DI group. Anastomotic leakage (AL) was identified in three patients who underwent GI, and in all of them, GI was easily converted to DI. There were 96.3% of the patients with DI rehospitalized at least one time because of surgery-related and/or stoma-related complications or stoma closure. When we did not take into account the patients who were rehospitalized for stoma closure, the rates of rehospitalization were 4.7% and 22.2% in the GI and DI groups, respectively (P= 0.01). The mean total costs calculated by removing additional surgical procedures and adding all of the rehospitalization costs were 25,767 USD and 41,875 USD in the GI and DI groups, respectively (P= 0.0001).
    Conclusion: GI may be a safe and cost-effective method in patients who underwent LAR with low or medium risk factors for AL. It is possible to avoid unnecessary ileostomy and reduce unwanted outcomes due to it, such as postoperative complications, rehospitalizations, and increased total costs by performing GI.

    Abstract Appendiceal intussusception (AI) is a difficult disease to diagnose. Various features of the disease were analyzed in a 35-year-old female patient admitted with abdominal pain and diagnosed with AI. The diagnosis was made with colonoscopy and abdominal computed tomography. Laparoscopic partial cecum resection was performed. Pathology examination revealed foci of endometriosis externa, which infiltrated the muscular layer of the appendix. AI should be kept in mind in the differential diagnosis of recurrent abdominal pain. Colonoscopy is an indispensable examination for differential diagnosis. Laparoscopic partial cecum resection, preserving the ileocecal valve, is an appropriate treatment approach in irreducible cases that are not suspected to be malignant.

    Abstract Background: The location of colonic tumors has been linked to different clinical and oncologic outcomes. Transverse colon cancers are generally included as right colon cancers. Furthermore, hepatic and splenic flexure tumors are usually included as components of the transverse colon.
    Objective: This study was aimed at comparing the clinicopathologic characteristics and long-term outcomes between mid-transverse and right and left colon cancers and determining the prognostic impact of the primary tumor location in the mid-transverse colon.
    Design: This was a retrospective study.
    Settings: Two specialized colorectal centers were included.
    Patients: Patients who underwent curative surgery for colon cancer were analyzed. Tumors located in the transverse colon, excluding the flexures, were defined as mid-transverse colon cancers.
    Main outcome measures: Demographic characteristics, operative outcomes, pathologic results, and long-term outcomes were the primary outcome measures.
    Results: Of the 487 patients, 41 (8.4%) had mid-transverse, 191 (39.2%) had right, and 255 (52.4%) had left colon cancers. For mid-transverse colon cancers, the mean length of hospital stay, mean length of the resected specimen, and the mean number of harvested lymph nodes were significantly higher. For patients with stage I to III cancer, the 5-year overall and disease-free survival rates were significantly worse in the mid-transverse colon cancers than in the right and left colon cancers (overall survival: 55.5% vs 82.8% vs 85.9%, p = 0.004, and disease-free survival; 47.7% vs 72.4% vs 79.5%, p = 0.003). After adjustment for other clinicopathologic factors, mid-transverse colon cancers were significantly associated with a poor prognosis (HR = 2.19 [95% CI, 1.25-3.83]; p = 0.006).
    Limitations: Molecular and genetic information were unavailable in this retrospective study.
    Conclusions: In our case series, colon cancers located in the mid-transverse colon showed poorer prognosis than cancers in other locations. The impact of tumor location in the mid-transverse colon on prognosis, including molecular and genetic markers, should be investigated further in prospective studies.

    Localizacin transversa media en el tumor de colon primario un factor de mal pronstico: ANTECEDENTES:La ubicación de los tumores de colon se ha relacionado con diferentes resultados clínicos y oncológicos. Los cánceres de colon transverso se incluyen generalmente como cánceres de colon derecho. Además, los tumores del ángulo hepático y esplénico suelen incluirse como un componente del colon transverso.OBJETIVO:Este estudio tuvo como objetivo comparar las características clínico-patológicas y los resultados a largo plazo entre los cánceres de colon transverso medio y derecho e izquierdo y determinar el impacto pronóstico de la ubicación del tumor primario en el colon transverso medio.DISEÑO:Este fue un estudio retrospectivo.AJUSTE ENTORNO CLINICO:Se incluyeron dos centros colorrectales especializados.PACIENTES:Se analizaron los pacientes que fueron sometidos a cirugía curativa por cáncer de colon. Los tumores ubicados en el colon transverso, excluidos los ángulos, se definieron como "cánceres de colon transverso medio".PRINCIPALES MEDIDAS DE RESULTADO VOLARACION:Las características demográficas, los resultados quirúrgicos, los resultados patológicos y los resultados a largo plazo fueron las principales medidas de resultado valoracion.RESULTADOS:De los 487 pacientes, 41 (8,4%) tenían cáncer de colon transverso medio, 191 (39,2%) derecho y 255 (52,4%) cáncer de colon izquierdo. Para los cánceres de colon transverso medio, la duración media de la estancia hospitalaria, la duración de la muestra resecada y el número medio de ganglios linfáticos extraídos fueron significativamente mayores. Para los pacientes en estadio I-III, las tasas de supervivencia general y sin enfermedad a 5 años fueron significativamente peores en los cánceres de colon transverso medio que en los cánceres de colon derecho e izquierdo (supervivencia general: 55,5% frente versus a 82,8% frente versus a 85,9%, p = 0,004 y supervivencia libre de enfermedad; 47,7% frente a 72,4% frente a 79,5%, p = 0,003, respectivamente). Después del ajuste por otros factores clínico-patológicos, los cánceres de colon transverso medio se asociaron significativamente con un pronóstico desfavorable (Razón de riesgo: 2,19; intervalo de confianza del 95%: 1,25-3,83; p = 0,006).LIMITACIONES:La información molecular y genética no estuvo disponible en este estudio retrospectivo.CONCLUSIONES:En nuestra serie de casos, los cánceres de colon localizados en el colon transverso medio mostraron un peor pronóstico que los cánceres en otras localizaciones. El impacto de la ubicación del tumor en el colon transverso medio sobre el pronóstico, incluidos los marcadores moleculares y genéticos, debe investigarse más a fondo en estudios prospectivos.
